Quasi-static analysis of the shielded microstrip line with bi-isotropic substrate by the strong FEM formulation

The paper presents the calculation of the effective relative permittivity and the characteristic impedance of the shielded microstrip line with bi-isotropic dielectric substrate, and with the special kind of the bi-isotropic substrate - the Tellegen material. Calculation was performed using the strong formulation of the Finite Element method (FEM). Basis functions of the third order and rectangle mesh were applied.
